I am a tarot card reader and all my reading have come true except few!
What could be the reason?
I did reading for a girl and all predictions came true except one. I would like to know how could this happen?
I do trust my cards and in divination but a prediction coming out untrue is hard to digest
It seems to me you need to back up a bit to take a new and wider approach to get the real truth of the situation here...
First, how would one know if they got all readings true? You don't, you never will; assume you didn't. First off, that will keep you humble and from appearing foolish, young and inexperienced. Secondly it will keep your eyes and brain open to experience and to utilize better approaches in the future. People are prone to tell you what is easiest to tell you, whether that be true or false. They will possibly at times tell you that you were right if wrong, or wrong when right. Don't go by what people say.
If you are judging by what you see, that can be deceiving to the nth degree; you certainly can't trust your eyes for a clear analysis of any given circumstance, after all, what they see must be interpreted by your brain, based upon your life experience. That then is a tainted view, isn't it? So what you need to do is understand that the Tarot isn't consistently provable as either accurate or inaccurate. That you either have your own reasons to keep faith to follow your journey in Tarot through, or you don't and must move on to what floats your boat.
If everyone whom ever attempted to read Tarot could get 100% accuracy, which as pointed out is impossible for the best of readers; then just about everyone would be doing it. Really. You need to know that there is great value in allowing oneself to be inaccurate and accepting it with grace. As long as you occasionally feel what it feels like to be wrong, it will keep you striving to be right. If you didn't have that, how would you keep learning? How often we meet Tarot readers with many decades of experience that still read, do and experience all they can; this in their hungry pursuit of higher knowledge of the Tarot.
How rare it is we meet someone, even with decades of experience within the world of Tarot that professes themself to be 100% accurate, or lets be more logical, 90 or even 85% (the highest rate of accuracy possible is 70%) accurate. It absolutely shouldn't enter into how you find your faith to continue learning. My advice? Use Tarot to grow spiritually, just because you can; therein lies its true value. Be thankful that for a side-dish you get a free serving of divination. Blessings to you in your journey through the Tarot!
